[166][167] A 2010 study conducted at Argonne National Laboratory reached similar findings, concluding that PHEVs will reduce
oil consumption but could produce very different greenhouse gas emissions for each region
depending on the energy mix used to generate the electricity to recharge the plug - in hybrids.
But if one looks at growth projections for
oil consumption, hybrids will slow the growth rate of
oil imports only marginally, at best, with the amount
depending on how many hybrids are sold.
